March 19, 1935. -J: BLUMENF'ELD 3 SHOE INSOLE LAYER Original Filed March 10, 1951 Patented 'Mar. 19, 1935 1,994,681 SHOE msoLE LAYER Julius Blumenfeld, Ebernburg (Pfalz), Germany Application March 10, 1931, Serial No. 521,595. Renewed November 23, 1934. In Germany July Claims;

The invention relates to a shoe insole layer or a shoe provided therewith. The principal object of the invention is to provide an elastic support and at the same time prevent the foot from be- 5 coming moist by perspiration, this being done by a flow of air. A further object of the invention consists in that treading on a pointed object is not perceptible. A further advantage of the invention consists in that the so-called elastic tread (lining or the like) previously provided below the inner soles can be omitted.

The insole layer, according to the invention consists of a layer of solid rubber of cellular structure which supports the inner sole by means of the thin cell walls. The flat tread surface which is formed by the cell walls is much smaller than the surface of the cellular cavities, whereby the grid-like supporting ribs of the insole layer provides great elasticity. The cellular cavities of the insole layer are open above and thus provide air exchange with the interior of the shoe.

Fig. 1 is a cross-section through a shoe provided with the insole layer. Fig. 2 is a perspective view of the insole layer.

The insole layer 17, c is provided between the insole a and the sole proper e. The cells of the insole layer are open above and the inner sole is provided with openings in order to render possible exchange of air between the interior of the shoe and the cellular spaces. The insole layer forms a completely flat grid-like tread or supporting surface for the inner sole a. The grain can be removed from the inner sole 11, whereby the latter becomes permeable to air, in which case it is not necessary to provide special air exchange openings in the inner sole. During walking a pumping action takes'pl-ace through the compression and expansion of the layer b, c; and the resulting air flow keeps the foot .dry and cool.

According to Figs. land 2, the insole layer consists of cell walls b which form a grid-like extension of the rubber sheet 0. The rubber sheet or foil 0 is turned toward the sole proper or outer sole e and prevents moisture from penetrating through the layer into the cells and thereby into the interior of the shoe. The rubber sheet 0 may also be replaced by any other water proof material.

I claim':

1. In a boot or shoe the combination with an inner sole-and an .outer sole, a layer of solid rubber having a grate-shape surface interposedbetween said inner and outer sole, the upper and lower surface of said layer being parallel to each other, said layer supporting the inner sole by means of the grate-shape surface, said grateshape supporting surface being much smaller than the area of the cellular cavities of the grate-shape surface and said inner sole being adapted for air passage.

2. In a boot or shoe, the combination with an inner sole and an outer sole, a layer of solid rubber interposed between said inner and said outer l0 sole, said layer consisting of a foil and cell-walls protruding therefrom and forming a grate-shape surface, the upper surface of said cell-walls be ing parallel to the lower surface of said foil, said foil being placed adjacent to the outer sole and 15 said cell-walls supporting the inner sole, the supporting surface of thesecell-walls being much smaller than the area of the cellular cavities co fined by these cell-walls and said inner sole being adapted for air passage.

3. A shoe insole layer of solid rubber having upstanding ribs on one side forming a grate, the upper edges of these ribs being parallel to the lower side of the layer, said ribs supporting on their upper edges a second layer, this second 25 layer being adapted for the passage of an air flow, the supporting surface of the said ribs being much smaller than the area of the cellular cavities of the grate formed by these ribs.

4. In a boot or shoe, the combination with an 30 inner sole and an outer sole, a layer of solid rubber interposed between said inner and outer sole, said layer consisting of a foil and cell-walls protruding therefrom, the upper edges of said cell walls being parallel to said foil, said foil being 35 placed adjacent to the outer sole, said cell-walls forming a grate and supporting the irmer sole, the supporting surface of the said cell-walls being much smaller than the area of the cellular cavities of the grate and said inner sole being 40 adapted for air passage.

5. In a boot or shoe, the combination with an inner sole andan outer sole, a layer of solid rubber interposed between said inner and outer sole, said layer consisting of a foil and cell-walls protruding therefrom, forming a grate having polygonal cavities, the upper edges of these cell-walls being parallel to said foil, said foil ,being placedadjacent to the outer sole, said cell-walls supporting the inner sole, the supporting surface of the said cell-walls being much smaller than the area of the polygonal cavities of the'grate and said inner sole being adapted for air passage.
